An exercise device includes at least one arc-shaped wing structure shaped to conform to a curvature of an exterior surface of an exercise ball such that when applied to the exterior surface thereof the at least one arc-shaped wing structure has a lower proximal end and an upper distal

An exercise device includes a central hub, a plurality of rib structures radiating from the central hub, and a band. Each rib structure has a proximal end secured at the central hub and terminating at a distal, radiating end. The band is secured to the distal end of each rib structur

A handheld, vibratory exercise device with a handle that has a low center of gravity and selectively removable modular weights for incorporating an adjustable and additional resistance. The present invention is a vibratory system with a hand-held resistance device that may have a pen

An exercise device includes a body having rib-like structures and an annular band. Each rib-like structure has an exterior surface defining a longitudinal extent, terminates at a radiating end, and has at least one wing formed substantially parallel to the longitudinal extent and pro

An exercise device for controlling the rolling movement of a stability ball during exercise. The exercise device has a central base, a plurality of rib-like structures radiating from the central base, each rib-like structure having at least one wing, formed substantially parallel to a
